WILLIAM ROMBAUGH AND JAMES O. MEARS, OF OLIVET, PENNSYLVANIA.

IMPROVEMENT IN TRACE-FASTENERS.

Specification forming part of Letters PatentlNo. 146,206, dated January 6,1874; application filed June 28, 1873. i

To all whom twmay concern:

Be it known that we, WILLIAM RoMBAUcn and JAMES C. MEARS, of Olivet, in thecounty ot' Armstrong and State of Pennsylvania, have invented a new and Improved Trace-Fastener, of which the following is a specication:

In the accompanying drawing, Figure l represents a side View of our improved single-tree hook attached to the end of the tree, and Fig. 2 is an end view of the same.

Similar letters of reference indicate corre spon ding parts.

T he invention consists in improving the construction of trace-fasteners, as hereinafter described, and pointed out in the claim.

In the drawing, A represents the sin gle-tree, to each end of which is applied shoulder B and hook C. The shoulder B is screwed into the tree fby a threaded bolt, a, and bound firmly therein by ring or ferrule b. The outwardly-projecting part of shoulder B is provided, at the sideadjoining t-ree A, with a circular recess, d, for hook G. The lower side of the shoulder is also recessed to produce, with hook C, the open space for the trace. The outer edge of shoulder B is grooved at e, for the pointed end of hook C, when the trace is attached and the hook closed. The hook C consists of the linkshaped end f, which turns by cross-piece f' in recess d of shoulder B and hook-end g, which is pointed, so that the trace slips easily over it. Hook O is swung up sidewise on shoulder B into the longitudinal direction of tree A, in which position the end of` the trace, whether it be ot' leather, or an iron v ring, or other piece, may be slipped easily over the pointed end g. The hook C is then turned over, so as to be under right angles to treeA, and forming a link-shaped piece with shoulder B, from which the trace cannot release itself, being held securely inclosedtherein. As there is hardly any friction, the trace and hook last a great deal longer than the ordinary hook, especially as the construction is strong and liable to resistany strain thereon.

Having -thus described our invention, we claim as new and desire to secure byLetters Patent- A piece, B, on the end of the whiflietree, provided with grooves d e, combined with the hook C, which is pivoted in groove d, straddles piece B, and is movable in a plane passing through the axis of the whiietree, as described.
